My invention 'relatesto new and useful improvementsin. sectional waterheaters of 'that'gtype wherein a'plurality of independently formedsections are used either as a hot .Watertheater QrJsteam boiler. v

"The object of the inventionis to provide a novel construction offurnace that is es} peciallyadapted forburning oil, and wherein a seriesofflues are provided that extend through'the'length of the furnace sothat an increased surfacetarea of the boiler will beexposedto"thefiameand products of com 'bustionfrom the fuel in a mannerto betterextractthe' heat therefrom.

Affurther feature ofthe invention is to first pass the'fire through theupper sections of. thefurnac e,.an'd then down through itslow-er.portions'wherei the water is naturally "coolest, and finallydischarging the smoke outfrom the lower portion after the heathas;practically .all been extracted there "from. *By'this arrangement, theproducts of combustion, as they passfrom the combustion chamber, areexposed to'theupperpart of the boiler wherethe water is naturally thehottest, and then when cooler passes down through the lower portionwhere .thereturn incomingwater is naturally cooler.

Afurther object of my invention is to design a furnace which ismoreoriless elastic, that is to say, one which readily lends itself to;theconstruction of boilers of different sizes and heating capacity,in-which a suit ablenuniber of intermediate sections-may be employed inaway to forma longer or shorter boiler.

The :essential and characteristic features ofthe zinventionlareobviously susceptible of modification, 'the illustration shown intheaccompanying drawings being a preferred embodiment of thefinventiomas will be better understood from the following description wherein.references' made to the accompanying drawings of which .Fig. .lshows aperspective view -of my improved furnace, .as .it will appear whenenclosed. by .asuitable .sheetmetal casing;

Fig. 7 showsafurther sectionalplanview through the lower portion of the.assembled units taken on2line.77 of Fig.2; and 7 Fig. 8 shows a detailedsectional .viewillustrating one of the sleeve connections employed incoupling the sectionstogether.

Referring first to 'Fig. ,4: of the drawings wherein is illustrated fivec esmetal -sections, as used in the construction of a'boiler of specificcapacity, are separately illustrated, it will be observedthat thefrontsection A and the rear section'B are different and that the intermediatesections C,.of which but three are shown,are alike in: constructionthough different from either oftheend sections. This obviously makes itpracticalito employ a greater or. lessennumber of. the intermediatesections to form'a boiler. of greater orlesser capacity.

-Each-of1these sections formsrin itselfa water containing unit, and whenassembled in series and secured together in the manneril- 9o lustratedin Fig. .2, formsa common water chamber 10 byreason of thenipples-connecting the upper andlower portionsof the several sections.Theseassembled sections form a central longitudinalcombustion chamberand associated fiues, service or feed pipe outlets 11, return inlets12,.tapped holes l3for the attachment of an altitude-.gaugelt, and othertapped holes 15 for the attachment of try-cocks l6 and additional holes17' for a 100 gauge glass 18, all of which are more or less employed infurnaces of this eneral type. The tapped hole 19 is for the attachmentof an aquastat which is used as a safety device for both hot water andsteam heating. 20 represents an opening for application of a stackcontrol, not shown, and 21 represents a further hole which serves as anoutlet through which the boiler may be emptied. If the boiler is used assteam boiler, it would require a safety valve and other accessoriescommon to that class of boiler, but which I have omitted from thedrawings.

It will also be obvious that the assembler unit, as shown in 2, may becovered in any preferred manner, and with any preferred material such asa preliminary coating of plastic or sheet asbestos that may or may notbe covered with a sheet metal casing 22, as illustrated in Fig. 1.

Referring first to the general consti ction of the heater, as shown inFigs. 1, 2 and 4, and formed of the several conne t d sections, it willbe noted that 23 represents the main combustion chamber which may or maynot be lined with fire brick, not shown. The front end of the combustionchamber is enclosed with a closure frame on which is hung a door 2?. Agun type or rotary form of oil burner 26, that may be of any preferredmake, is positioned in a hole 2'? of the frame and projected into thecombustion chamber in the usual manner.

The several lines which will next be referred to, and which for the mostpartextend through different portions of the boiler, are produced byforming openings through and in the several sections, which are locatedso as to properly register one with another when the sections areassembled in a way to form a continuous passage or flue from thecombustion chamber backward and forward and vertically to the smokeoutlet which is situated in the rear portion of the furnace.

Referring first to the fi nt section A, it will be seen that it isprovided with a central opening 28 therethrough, which like similaropenings 28 in the other sections, e;=: cept the rear section B. servesto form the combustion chamber. The said rear section is, however,provided with pocket 29, Figs. 4, 5 and 6, that is of a size andposition to register with the opening 28 in the adjacent section, andthus serves to form the closed rear end portion of the combustion.chamber.

The front section A. as well as t l e three intermediate (l-C. areprovided with a central open ng 30 tlierethro 93h immediately above thecombustion chanper 28 and adjacent the communicat n upper side openings3131, which openi u, like the combustion chamber openings, are similarlylocated and of like sizes and proportions so as to register one with theother when the sections assembled, and whereby a central upperlongitudinal flue 32 is formed that extends through each of the sectionsAC C-C and into a pocket 33 of the rear section B, the forward end ofthe said flue 32 bein open into the forward end of the com bustionchamber through a vertical opening 84, see Figs. 4 and 5, and wherebythe products of combustion from the combustion chamber flow up into thecentral longitudinal flue 32 and back into the pocket where it returnsand comes forward, see arrow Fig. 3, into the longitudinal flues 3535.The front end of said lines, as well as the other openings through thefront section A, being closed by the metal casing 22 and doors hungthereon, as shown in F 1.

Each of the adjacent side faces of the several sections are providedwith vertical concaved recesses on either side of the combustionchan'iber openings which, like the said openings and fines areproportioned and positioned to register with each other, see Fig. 6 whenthe sections are assembled, and for the purpose of forming a series ofvertical lines 36 which extend down on either side of the combustionchamber from the before mentioned upper longitudina flues 35 and connectwith the lower outer longitudinal flues 3'? that are formed by theopenings 38 in the lower corner portions of the several sections. Thetwo openings 38 through the front sec tion A, see 4 and 7, arerelatively wider than the openings 38 through the intermediate sectionsso as to form a return into flue 89 from the longitudinal flue 37 formedby openings 40 through the intermediate sections C and rear sectionThese openings in the last mentioned section B deflected inward to forma united smoke outlet or nipple 41 central of and the lower rear portionof the furnace.

Each of the vertical lines is provide with a clean-out opening 42through each portion of the adjoining sections, which openings arenormally closed by doors 43, see Fig. 1. The upper flues 32 and 35 areprovided with clean-out doors 44 while the lower lines 37 and 39 arealso provided wi h clean-out doors 45. The connecting openings to insurea circulation of water through all the sections are preferably formed bya series of aligned holes 46 through both the central top portion of thefurnace and the lower central portion, the customary form of nipples 47being employed to insure prop-er watertight connection as Jetwcen thesections. The sections may also be secured together in the usual way bytierods 48, two of which extend across the top of the sections andengace holes in flanges of t. 0 front and rear sections while the lowerrods are preferably located in the flues 39 and have their end portionsengaged with the end sections, one end of the rods being threaded andprovided with a nut whereby sectlons may be drawn together.

It is to be noted that in the formation of larger number of fines thatextend longitudinally through the furnace than 1s customarily found incast metal types of boilers, but has I arranged the same so that theJroducts or combustion first pass and repass through the upper portionof the furnace above the combustlon chamber and are then carried downber to longitudinal lines in the bottom portion of the furnace which.again serve to carry the products of combustion forward and backwardthrough the boiler.

It is also a feature of the design of ap-' plicants boiler that allwalls of the sections, which are exposed on the one side to the heat orproducts of combustion of the boiler, also serve as a wall for water inthe furnace in a way to quicker consume all the heat from the smokebefore it is discharged into the chimney and thereby more efficientlyheat the water.
